We have Digium phones and have recently removed the last few D70s from DPMA control. We are using Endpoint Manager now.
Since removing the receptionist's D70 from DPMA control, paging no longer works. I assume that Digium phones still don't support Multicast (went round and round on this a couple of years ago) and so I am not clear on how to get a basic paging group up and running with these.
We have a mix of D40, D50 and D70 phones. We have a couple of Yealinks and other brands around and they are working fine with the basic paging setup, but we are 98% Digium.
